fix(docs-bootstrap): Removed injector from bootstrapped docs samples.

[jeffbcross]

This is necessary to make e2e tests pass for implementing #3411. At present, the docs are violating the rule being enforced by double-bootstrap prevention.

There's still some work to be done before merging:

• Write unit tests
• Implement feature
• Pass all new and existing tests on CI

Perhaps we should add a little jqLite unit test in for this?

[jeffbcross]

Yes, Misko and I put this together in a hurry and I added some todos in my PR message to come back to this when time frees up.
